MACHINE FOR MAKING FASTENERS.

Application filed June 4, 1923, Serial No. 643,268. Renewed February 18,1928.

This invention relates to means for making and fastening clasps on afabric strip, and the objects of the invention are to provide animproved means whereby clasps are punched and individually delivered toa fabric strip and placed and fastened thereon in a continuousoperation, and the fabric is thereafter wound on a spool ready for anyuse to which it may be applied, such as on garments, bags, and otherarticles too numerous to be specifically mentionedherein.

Further objects are to simplify the con struction of the mechanism andproperly time the several parts so that they will synchronize andautomatically cooperate, in this way increasing the efficiency and wellworking of the machine.

Further objects still are to render the machine compact in construction,economical, and to so arrange the several parts that they are accessiblefor inspection and repair, and generally to adapt the several parts tobetter perform the functions required of them.

With the above and other objects in View which will be made clear as thespecification proceeds, my invention consists in the improved means formaking and fastening clasps on a fabric strip, such as is described indetail in the following specification, illustrated in the drawings andmore particularly pointed out in the appended claims.

For a better understanding of my invention reference is now made to thedrawings in which Figure 1 is a tire machine.

Fig. 2 is a side elevation of the same.

Fig. 3 is a vertical section taken on the line 33 of Fig. 1. a

Figure 4 is an enlarged fragmentary view of the carrier and feedingmechanism.

Figure 5 is an enlarged fragmentary sectional view taken on-the line 5-5of'Figure 1-.

Figure 6 is a fragmentary sectional view taken on the line 66 of Figure5.

Figure 7 is a diagrammatic view showing the various steps of the claspssetting and fastening means'in operation.

Like characters of reference refer to like parts in the drawings. I

Referring to the drawings,-I have illustrated'conventionally a powerpress 8 embodying well'known mechanical arts which it is not deemednecessary to ilustrate or general plan view of the endescribe, the press8 being provided with a pulley 9 which may be driven from any suitablesource of power.

In front of the press 8 I have arranged a pair of feed rollers 11 whichare properly timed and actuated by the press so that they synchronizewith the movement thereof, and the band of metal 10 is fed to the feedrollers 11 step by step so that clasps are punched from the band duringthe progressive feeding thereof.

The metal band 10 is fed to the punching and forming dies 12 and eachclasp as it is punched is automatically picked up and delivered to aconveyor by the rocking arm 51 which is mounted beneath the said dies.

This rocker arm is provided with an arm 52 which is connected to one endof a spiral spring 52, the other end of which is secured to a convenientpart of the power press, and i the rocker arm is also formed with aprojection which coacts with a stop 53.

' This rocker arm is actuated by an adjustable member 49 operativelyattached to a reciprocating part 48 of the power press 8, and thismember engages the projection 50 and rocks the arm in one directionagainst the action of the spring 52, and the movement of the arm in theopposite direction is limited by the stop 53.

The rocker arm 51 whenactuated by the member 49 engages the punchedclasp and delivers it to the conveyor and to this end the rocker'armextends into a slot in the end of the carrier portion 14 of the conveyoradjacent-to the power press.

The conveyor consists of a carrier 14 formed of an elongated strip ofmetal having its lateral edges bent to overhang the body of the strip,the said edges being spaced to form a central passageway. or guide 2 foran object to be made clear hereafter.

Coperating with the carrier 14 is a feeder 13 provided on onelongitudinal edge with serrations from which fingers 22 depend into thepassageway or guide 2, to engage the clasps in the carrier 14, and thisfeeder is formed on the opposite longitudinal edge with projections orlugs 3 which carry a rod 4 slid- -1ng y mounted in brackets 5 secured tothe base 45 of the machine.

This feeder is designed to be reci rocated and is provided with a collar20 a justably mounted on the rod 4, the collar being connected to oneend of a spiral spring 21 the other end of which is attachedto a bracket5.

and driven by a chain drive 17 from the power press 8.

The feed'er is thus positively fed forwardly by the cam 18, and theretrograde movement a is brought about'by the spring 21.

As the feeding of the c asps is in a step by step movement, the feedingsteps are made during the forward movement of the feeder, and the feederis tilted about the axis of the rod 4 during the retrograde movement ofthe feeder thereby disen aging the fingers 22 from the clas s, and t efingers enga e other clasps at the eginning of the next orward stroke,so that in this way a positiveprogressive feeding of the clasps alongthe carrier 14 takes place. V

By forming the carrier 14 with overhanging side walls the path of travelof the clasps is welldefined and lateral displacement of the clasps isimpossible. v

i The tilting of the feeder 13 is accomplished by a projecting pin 23depending from the feedgi which pin coacts with the pivotally mountedplate 24 which is spring pressed into the path of the in during theretrograde movement of the eeder.

This plate is formed with'an inclined plane 26, which when the pin 23 isriding :thereover causes the feeder to be ti pedlaterally to disengagethe fingers'22 fi om the; clasps, and after the pin 23 has becomedisengaged from the inclined plane the fingers 22 engage the adjacentclasps to carry on the feeding operation.

The plate 24 is displaced laterally during the forward stroke of thefeeder by t e pin 23 engaging the --back of the plate, and as soon asthe pm passes the plate, the said plate is sprin pressed back intonormal position so that the inclined plane 26 is in the path of the apin 23 on the retrograde movement of the feeder.

As the clasps reach the end of the carrier 14 they are positioned on afabric strip 34 which is fed across the path ofthe clasps through a slotin the end of the carrier.

This fabric strip is unwound from a bob- I bin 47 supported from thelower side of the base 45, and the fabric-strip passes around a springcontrolled tension pulley 46, after which it passes between the chargingwheel 43 and the coactitng roller 44, the fabric strip being then woundon the bobbin 42. Y

The movement of the fabric strip synchronizes with the movement of theconveyor which delivers the clasps to the said strip;

To bring about this movement 'of the-fabric strlp Iomount cams 27 on theshaft 16 and these cams coact with the rollers 28 mounted on theends=othelongitudii1al arms 29 and 30, the opposite ends of the armsbeing engaged byp springs 36 which tend to press the rollers 28 againstthe face of the cams 27.

The arm 30 is provided intermediate of its length with a cam 37 whichengages a roller 38 carried by a slide- 39, one end of which is fixed toan upright arm 40 carrying at" its upper end a ratchet means 41actuating the charging wheel 43 whereby the fabric strip is fed from onebobbin to the other across the path of movement of the clasps on thecarrier 14.

The slide 39 is spring controlled in one direction so that the rollers38 will properly engage the cam 37.

' The arms 29 and 30 are each provided with cams 31 which engage withthe spring controlled roller 32 carried by the setting members 33 whichare arranged in'pairs working in unison to position and fasten theclasps on the fabric strip 34.

The slotformed in' the carrier 14 has, all along where the fabric strippasses through at 35, slightly overhanging edges to prevent the claspsfrom jumping out and becoming displaced, the facing ends of the settingmembers 33 being also made with slightly overhanging edges so as tosecurely hold the clasp while it is being fixed to the fabric strip 34.

The cams 31 have a dualaction upon the member 33 which are normally heldapart to clear the moving fabric strip 34, the first step of the actionbeing to localize and hold the clasp to be set in position, and thesecond step to properly set and fasten the clasp to the fabric strip 34.

The operation of the machine is as follows:

The band of metal 10 is fed to the rollers When a clasp has thus beenplaced on the carrier14 it is engaged by the fingers 22 of thereciprocating feeder 13 and positively fed in a step by step movementalong the carrier.

en a clasp reaches the end of the carrier it is straddled on the fabricstrip 34 and fastened thereon by the set-ting members, and the fabricwith the clasps is fed to the bobbin 42 and wound thereon ready for use.

Fromthe above description it will be seen that I have invented asimplified means for making and fastening clasps on a fabric strip themeans being such that it is simple in construction, readily accessible,practically foolproof, and not liable to go out of repair.

- What I claim as my lnvention is:

.1. A device of the class described, means for stamping clasps from aprogressively fed delivering the elasps to a carrier, means foractuating the rocker arm, a feeder for moving the clasps progressivelyalong the carrier,

means for feeding a strip of fabric across the a strip of fabric acrossthe carrier at the end thereof, and means for placing the clamps on thefabric and fastening them thereon.
